 Almost the same as sub2ind, except always returns only a single output
 that contains all the subscript locations.  Also handles multiple linear
 subscripts at the same time more conveniently then matlab's version. See
 help for sub2ind for more info.

 USAGE
  ind = sub2ind2( siz, sub )

 INPUTS
  siz     - size of array into which sub is an index
  sub     - sub(i,:) is the ith set of subscripts into the array.

 OUTPUTS
  ind     - linear index (or vector of indicies) into given array

 EXAMPLE
  ind = sub2ind2( [10,10], [10 2] )      % 20
  ind = sub2ind2( [10,10], [9 2; 10 2] ) % 19, 20
